// This file includes the additional plug-ins that can be added to the jQuery DataTables.


//------------------------------------------------------------------------------------------------------------
// By default DataTables only uses the sAjaxSource variable at initialisation time, however it can be useful 
// to re-read an Ajax source and have the table update. Typically you would need to use the fnClearTable() and 
// fnAddData() functions, however this wraps it all up in a single function call. Note: To reload data when
// using server-side processing, just use the built-in API function fnDraw rather than this plug-in.
